摘　　要：光纤故障定位是光纤通信网络正常运行的重要保障,提高光纤故障点定位的精准性,迅速将线路阻塞排除,降低经济损失是当前的一项重要课题,对此,文章结合光纤故障点定位的困难,提出一种利用电子地图与光时域反射仪OTDR相互配合来实现光纤故障点精准定位的方法,该方法以无源光纤网络PON为对象,基于OTDR对其光纤故障进行集中诊断与测量,同时,结合电子地图中较为成熟的GPS定位技术,实现对故障点的定位。Fiber fault location is the important safeguard to fiber optic communication network normal operation,nowadays,fiber fault location accuracy’s enhance,line blocking exclude and financial loss’s reduce are important tasks.The paper proposes a kind of method that combine electronic map and OTDR to locate fiber fault location,it makes PON as object,uses OTDR to diagnose and measure fiber fault intensively,and then uses GPS technology in electronic map to realize fault point’s location.
